Printing solar-cells

NANOSOLAR: Solar-cell Coating“The PowerSheet is made from a layer of solar-absorbing nano-ink that is printed onto a foil-thin metal sheet. According to the company, this technology has several key advantages. It is cheaper to make, as the process can produce several hundred feet of solar panels per minute, making it viable to generate a watt of electricity for less than $1, almost cheaper than what it would cost to produce by burning coal.”Inhabitat
